最近看了一些淘宝购物车的demo，于是也写了一个。
效果图如下：
主要代码如下： actvity中的代码：
public class ShoppingCartActivity extends BaseActivity {
private ListTest data;
private ListView mListView;
private ShoppingCartAdapter adapter;
private RelativeLayout rlRefresh;
private TextView tvRefresh;
private ProgressBar barRefresh;
private LinearLayout clear;
private CheckBox checkBox_select_all;
private CheckBox checkBox_add;
private TextView integral_sum;
private int sum = 0;
private int[] sumIntegral;
private Context context;
@Override
protected void onCreate(Bundle bundle) {
// TODO Auto-generated method stub
super.onCreate(bundle);
setContentView(R.layout.activity_shopping_cart);
initView();
}
private void initView() {
context = this;
showpage = 1;
isPermitFlag = true;
data = new ArrayListTest();
// 测试数据
data.add(new Test(id, color, type, 100));
data.add(new Test(id, color, type, 200));
data.add(new Test(id, color, type, 300));
data.add(new Test(id, color, type, 0));
data.add(new Test(id, color, type, 300));
data.add(new Test(id, color, type, 100));
data.add(new Test(id, color, type, 500));
data.add(new Test(id, color, type, 0));
data.add(new Test(id, color, type, 900));
adapter = new ShoppingCartAdapter(context, handler, data);
sumIntegral = new int[data.size() + 1];
checkBox_add = (CheckBox) findViewById(R.id.checkbox_add);
integral_sum = (TextView) findViewById(R.egral_sum);
clear = (LinearLayout) findViewById(R.id.clear);
clear.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
data.clear();
adapter.notifyDataSetChanged();
integral_sum.setText(0 + );
checkBox_select_all.setChecked(false);
checkBox_add.setClickable(false);
}
});
checkBox_select_all = (CheckBox) findViewById(R.id.checkbox_select);
checkBox_select_all.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
HashMapInteger, Boolean isSelected = ShoppingCartAdapter
.getIsSelected();
Iterator iterator = isSel
